Great Gulf

A wide gulf in the western coasts of Middle-earth. It lay far to the south of the known lands in Middle-earth's northwestern parts, forming an important feature in the geography of Arda. It was also one of the world's most ancient features - the Gulf was already in existence when Melkor overthrew the Lamps of the Valar, in the time when the Valar still dwelt in the Hither Lands.
